Many thanks Reddy for your code.
Ii is very helpfull, although the problem is not overcome. The code you sent me deals only with the main window. In my case, and due to your help of yesterday, the problem with the main window was solved. My main problem now it to use the document on the TextEdit of the main window from childwindow withough having to upload it again.
If I have a fucntion such as "functionxxx" for example of the childwindow, how can I get the path to the text on the main window and its text? When I am compiling my initial code, the error message is that "No file name specified" and that MyMainWindow ist private in this context.
Any help? Please!
